Acoustic Imaging Pty Ltd
Navigation and pilotage in Sydney Harbour
- Acoustic Imaging Pty Ltd
- The Port Authority New South Wales
In Australia's largest port of Sydney, the fundamental enabler of shipping growth is operational efficiency. The Port Authority of NSW (PANSW) orchestrates every large vessel movement within and surrounding the harbour. This includes arrival, docking, anchoring and departure of large vessels (pilotage) and the investigation and mapping (charting) of underwater hazards to navigation. Gains in port operational efficiency translate to increased number, frequency, capacity, speed and safety of commodities and tourists moving into and out of the harbour on container ships and cruise liners whilst reducing power and fuel consumption for the maritime sector.
Acoustic Imaging (AI) is integrating Australia's SBAS into PANSW pilots' portable navigation systems (PPUs) and into PANSW hydrographic surveyor's seafloor mapping (charting) systems to measure the gains in efficiency that SBAS positioning of consistent and proven statistical quality will bring to PANSW port management. Gains will be realised through establishment of a clear, safe and efficient method of undertaking daily routines and operations as well as in the capability to forward model low probability unplanned events. For unplanned events, trustworthy positioning data can be relied upon to provide awareness of what remedial actions are instantly accessible.
Current positioning methods for PANSW pilots provide predictions of the ship's location relative to the most recent chart of the harbour These vary in quality. As a result, a pilot must rely upon his or her visual awareness for steerage decisions. SBAS can potentially provide pilots with a continuous aiding source of consistent and known quality. This provides PANSW with a firm understanding of the risk to associate with each pilotage activity. Decreased risk enables increasing the number of ships in the shipping lane and closer passage of arriving and departing ships.
Current positioning methods for investigating hazards and mapping the harbour floor do not provide PANSW hydrographic surveyors with consistently trustworthy positioning required for instantaneous identification and mensuration of potential navigation hazards to add to a navigation chart. The major inhibitor of real-time charting is the difficulty of communicating from land GNSS stationary receivers (used as a source of positioning) to a remote vessel in a busy harbour. Without consistent land communication all harbour data must be returned to office where the data undergoes statistical validation and remediation prior to approval. This can delay a ship movement, docking or anchoring event. SBAS, because it is delivered from space, has the potential to provide data of the required statistical consistency for instantaneous identification and location of navigation hazards affecting berthing boxes and shipping lanes.
Acoustic Imaging (AI) is a 20-year-old Australian owned and operated company with a track record of introducing innovative techniques to the maritime industry in Australia and internationally. PANSW's approach to ensuring high quality navigation safety in Australia's premier harbour provides an ideal platform for controlled testing of SBAS. AI and PANSW have a decade of constructive collaboration across many projects.
Maritime Industry Australia Limited
A comprehensive maritime assessment on the impact of an operational SBAS and the potential business critical applications
- Maritime Industry Australia Ltd (MIAL)
- Various MIAL members and connections for testing
As Australia's largest representative of maritime interests, Maritime Industry Australia Ltd (MIAL) is well positioned to deliver the broadest possible industry specific scenarios across both Australia and New Zealand.
MIAL's extensive membership base of maritime owners, operators and other stakeholders, provides the necessary maritime platforms to test the capabilities of the new Satellite Based Augmentation System (SBAS) from scientific and commercial perspectives. This is a flagship project for maritime.
The areas of marine application being tested are: commercial, cruise, Antarctic, offshore and construction.
A key aspect of the Maritime Australia and New Zealand (MANZ) SBAS Project is to determine if the new system is more accurate than the existing signals.
There are significant potential benefits to having the most accurate precise positioning system for the maritime industry, including: increased efficiency of vessel and port operations, reducing operating costs and enhanced safety of navigation to protect the environment and infrastructure.
However, the SBAS capability must be proven prior to the deployment of the new technology.
The project results will be available to assist the Australian and New Zealand Governments in their decision-making processes around whether to adopt the SBAS technology.

SBAS navigation benefits for New Zealand aviation system
- Airways New Zealand
- Aeropath New Zealand
- Auckland Rescue Helicopter Trust
- IQ Aviation
- Helicopters Otago Ltd (Trading name Heliotago)
The improvements in manned & unmanned aircraft navigational accuracy and integrity delivered by SBAS could provide safety and efficiency benefits to the New Zealand aviation industry. Airways New Zealand will utilise the flight inspection aircraft to verify the SBAS signal strength at controlled and uncontrolled aerodromes in New Zealand. This will be in the course of, and to the extent reasonably achievable within, the Airways group¿s scheduled flight inspection programme. The flight inspection equipment can also compare the real-time performance of augmented GNSS with conventional and performance based navigation technologies. Additional testing will be undertaken with rescue helicopter operators on assessing the benefits relating to medical centre and hospital helipad access including enroute helicopter routes during poor weather conditions.
It is proposed that SBAS receiving equipment provided by CRCSI be installed for testing in aircraft operating within the Airway¿s group¿s scheduled flight inspection programme only, except where additional testing is planned to be undertaken with helicopters. Aeropath, a subsidiary of Airways New Zealand, will undertake assessment of instrument approach procedures to assess improvements in minima which can allow aircraft to land at aerodromes in poor weather conditions when currently they have to divert or not operate at all. Airways will work with project collaborators as set out in the project plan to assess the potential benefits of the SBAS technology.
This will enable the signal coverage and reliability to be tested at controlled and uncontrolled aerodromes during the period March to June 2018. Testing will take place within New Zealand and the Chatham Islands if required.
Airways NZ will coordinate collection of data from SBAS receiving equipment. This includes comparison of SBAS data with data produced by Airways NZ existing flight inspection equipment, where relevant to assess the aviation benefits of SBAS to the New Zealand aviation system. This assessment will include tests as follows:
- Test the SBAS L1 and L1/L5 service coverage across the New Zealand aviation system. This would verify signal reception at all controlled aerodromes, some uncontrolled aerodromes and heliports, and some low-level IFR routes.
- Test the reliability of the SBAS L1 and L1/L5 signal in-flight for instrument approach requirements to enable revised minima for instrument approach.
- Assess the actual minima reduction from the use of SBAS at selected aerodromes. From this data assess the possible benefits from lower approach minima.
SBAS Benefits for Australian Aviation
- Airservices Australia
- The University of Melbourne
Airservices Australia is leading a project on behalf of the Australian aviation industry to illustrate the safety and efficiency benefits of SBAS to airlines, regional/general aviation, and medivac operations. The project will make use of the SBAS testbed signal to demonstrate the performance of the technology in an aviation context.
SBAS has the potential to provide a broad range of safety and efficiency benefits to Australian aviation, particularly to rural and regional Australia. This project aims to quantify these benefits and establish that the test-bed meets the performance requirements of aviation. However, verification of the testbed as a Safety-of-Life system is outside the scope of this project.
This project will:
- Demonstrate the compatibility of the testbed with current generation avionics in an operational context (L1 SBAS)
- Test the availability, accuracy, and coverage of the testbed signal from ground and airborne stations (L1 SBAS & L1/L5 SBAS)
- Assess the safety and efficiency benefits of SBAS to Australian aviation for a range of navigation and surveillance applications (L1 SBAS)
In particular, the project will focus on the use of SBAS approach procedures in regional areas with limited ground infrastructure to improve the safety of medical evacuations and air-work.
Technology Demonstrator of Augmented Differential Positioning using SBAS Technology integrated with HERE True SLI & LiDAR Road Data Reality Capture Platform for Highly Automated Driving.
- HERE Technologies
Location is a key enabler to all industries and as we progress to an autonomous world with highly assisted driving and truck platooning, the precision of how we need to capture location has never been more important. Location of white lines on roads, lane widths, bridge clearances, parking bays, car charging locations, and the precise location of cars and trucks moving on the road network with or without drivers are just a few examples.
GNSS or 'GPS' as we know it today in Australia is used by HERE Technologies to build advanced road maps however the precision required to build maps for autonomous use has to correct `GPS¿ positions manually using complex correction methods. Leveraging the Satellite-Based Augmentation System (SBAS) in the HERE True Reality Capture Platform for Highly Automated Driving (HAD) will alleviate the need to post-process the location data, enabling more rapid access for Australian's of these transformational technologies capable of reducing congestion and saving lives. This technology also has the potential to position Australia as a leader in clean safe autonomous solutions.
Within the trial, the HERE HAD Team has modified the interfaces on the Reality Capture Platform such that it can ingest a time synchronised position signal from the SBAS Technology. The SBAS Technology has been technically interfaced and software integrated into a single HERE True Vehicle operating on the east coast of Australia for the trial only. Throughout the trial, information will be gathered to assess the effort to achieve full quality certification and road safety compliance for use within the HERE Reality Capture Platform.

Identec Solutions Australia and New Zealand
SBAS Testing for Terminal Process Automation
- Identec Solutions Australia and New Zealand Pty Ltd
- DP World Australia Ltd
Knowing where containers are at a terminal requires positioning accuracy of less than the container width. Identec Solutions currently use local GNSS base stations to achieve this accuracy in a terminal environment. Currently, this is only possible with local GNSS base stations. This project will test whether SBAS can be used as a regional replacement for, or redundancy of, these local GNSS base stations. The project also aims to test whether SBAS can support improved transport efficiency in the terminal environment and cooperative vehicle safety applications, such as providing alerts when accidents occur.
SBAS for Connected Vehicles: The potential road safety and efficiency gains through the use of an Australian Satellite Based Augmentation System
- Curtin University
- Transport for NSW
- Roads and Maritime Services
- University of New South Wales
Existing standalone GPS used in everyday vehicles is not accurate enough to position a vehicle in a lane within the road network. This project will examine whether the ability of SBAS can help to determine vehicle location at the sub-metre level, meaning the lane the vehicle is travelling in can be identified. This level of information is required by transport agencies and vehicle manufacturers to support improved transport efficiency and cooperative vehicle safety applications, such as providing accident alerts and informing Intelligent Transport Systems.
